Is it permissible for the person who is junub (needing to bath from sexual relations) from the night before to fast along with his wife or other than that?

Answer:

The fast of the one that had relations with his wife during the night and is junub in the morning is correct. Likewise for the one that became junub due to a wet-dream during his sleep during the night – or day then his fast is also correct.

Likewise there is no harm upon him if he delays the bathing until the appearance of dawn. Rather the fast is nullified if he has intercourse during the day from the appearance of dawn until the setting of the sun.
